OK .. now it's time for me to sound stupid :moody: .. the battery will notify me when calibration is necessary? Calibrate what? The Duracell multi-fit camera battery provides long-lasting lithium-ion power for a range of camera makes and models, allowing hundreds of photos to be taken on a single charge. I went to buy an additional battery for my D5200 today. The specs call for the Nikon EN-EL14. the store did not have any 14's but I was told they do have some 14a's that are compatible. Used together with your Nikon D SLR, the camera's fuel gauge accurately displays the remaining charge and number of shots since the last charging

D5500のバッテリーだけは純正品が良いって知ってた？

The unit is also able to charge AA & AAA NiMH rechargeable batteries and USB enabled devices via the 5V 1A USB port.It worked as well as if not better than my 6-year-old original. Crucial tool when on vacation when access suitable charging isn't guaranteed.

These rechargeable batteries provide extended life and consistent power, even in colder conditions. What is the difference between the EN-EL14 and the EN-EL14a in regards to my D5200? Did I just make a bad decision? The one thing I did find out ( after doing A LOT of research ) is that the EN-EL14a will give me more frame shots than the EN-EL14.
